i managed to flash my 0272 (original 9504) with 1.91 using kamikaze-method.
but i didnt do a slimkey on the original firmware, is this important?
i flashed it using the full dump (lite-ofw.bin) as the original firmware.
also, what is this mysterious sector 0x3e0000?
here my story:
1) i flashed the 9504 with LT+ 1.0
2) flashed back to original, but not using full dump or dummy.bin because i couldnt find my original dump any more.
3) thus i dumped the LT+ 1.0 so i have my key and restored the OFW using the CFW.
4) flashed OFW
5) upgraded to newest dash.
6) ms flashed my device with 0272.
questions:
1then i just dumped the original 0272 using full dump ("read") and flashed cfw.
when i was asked for the 0x3e000 ("it may be blank"), i chose _no_ because my device had 0272 on it, was that correct?
2) to be on the safe side i flashed the OFW i just dumped and used the slimkey method to get the dummy.bin, serial.bin, inquire.bin, etc.
was that useful or useless?
somebody tell me if what i did was correct, and what sector 0x3e0000 is good for please.

i want to know if what i did is correct before i assemble my xbox.
thanks in advance,
